NAT and UDP packets #39

Open slater0013 opened 3 years ago

Hello,

Trying to use esp32_nat_router with a big wifi antenna connected to a WROOM_32U to extend my Drone range.

Installation is ok, configuration is ok.

But my drone is sending the video stream as an UDP feed. And I suppose the NAT router does not know to which client send it !

Is there any way to specify a "DMZ" NATed client that would receive every incoming packets, including UDP packets that are not in the NAT table.

Hope It's clear ?!

Thanks, GS.

No, there is no default client. You can define a portmap rule for any required UDP port.

Ok ! Any Link to a documentation in order to achieve such rules ? Thanks !

slater0013 commented 3 years ago

Sorry for asking again, any hints how to add such port redirections ?

You have to modify the code: add the call(s) to ip_portmap_add() after esp32_nat_router.c#L367

A DMZ mode would be great, as I'm also running a single client behind this. I don't know how much work a fully-transparent "repeater" mode would be (ie it just extends the current LAN by transporting packets back and forth, without NAT), but that would be ideal.
